Description
Technical Field
The present invention relates to the field of acoustic technologies, and in particular, to an uplink noise reduction earphone and a corresponding uplink noise reduction method for the earphone.
Background
At present, the earphone with the uplink noise reduction function is mainly realized by adopting an air conduction scheme, a bone conduction scheme or a scheme combining air conduction and bone conduction. The air conduction scheme mainly adopts a double-microphone or multi-microphone array mode to perform uplink noise reduction, and can perform certain consistency on background noise, so that the aims of enhancing voice signals and improving the communication quality are fulfilled. And the scheme of bone conduction or the scheme of combining air conduction and bone conduction adopts a bone conduction microphone capable of picking up human body vibration to pick up voice signals, so that the suppression of surrounding environment noise is more effective.
However, in practical applications, the noise reduction performance of the air conduction scheme is closely related to the noise conditions of the surrounding environment. When the signal-to-noise ratio is high, the noise reduction effect is good, and along with the reduction of the signal-to-noise ratio, the noise reduction effect is also reduced. For example, some air conduction schemes start to collapse when the signal-to-noise ratio drops to 0dB, i.e., when the energy of the speech signal and the noise signal are comparable, and most air conduction schemes fail to work properly when the signal-to-noise ratio drops to-6 dB in a strong noise environment.
Although the bone conduction solution can work in a strong noise environment, it is limited to the wearing position of the bone conduction microphone. For example, the farther away the wearing position is from the mouth or vocal cords, the more high frequency is attenuated, and the narrower the audio bandwidth, resulting in reduced speech intelligibility, or even inaudibility. In addition, the bone conduction scheme still requires that the product structure closely laminates with the human body, and it is relatively poor to wear the comfort level.

Then, the main control chip eliminates the interference signal of the vibration signal output by the laser sensor, for example, the interference from natural light or the vibration interference of other objects. After the interference elimination is carried out on the vibration signal, the vibration signal without the interference signal is analyzed through the main control chip to obtain the required vibration information, and the vibration information is analyzed to restore the voice signal contained in the vibration information, so that the final voice signal is obtained.
And finally, transmitting the finally acquired voice signal to an equipment terminal, such as a mobile phone, a bracelet, a pad and the like, and sounding through an earphone connected with the equipment terminal or a loudspeaker of the equipment terminal. Due to the fact that the precision of the laser sensor is high, tiny vibration can be picked up accurately, and therefore original voice signals sent by a user can be restored more abundantly and truly.
The main control chip can eliminate the interference signal in the vibration signal according to the frequency band difference because the frequency band difference between the interference signal and the vibration signal is large; in addition, various ways such as filtering and eliminating the interference signal by a filter may be adopted, and various improvements may be made on the processing of the interference signal without departing from the content of the present invention.
